TO ALL WHOM IT MAY CONGE-RN:

Be it known that I, DEXTER SYMoNns, of Lowell, in the county of Middlesex, and State of Massachusetts, have invented certain new and useful improvements in Lamps for Generating and Burning Gas, of which the following is a full, clear, and exact description, reference being had to the accompanying drawiugs,making.

part of this specification, in which is represented alvertical central section considerably enlarged.

In this invention the Huid-reservoir Avis arranged on the top of a vertical tube, B, the bottom end of which screws into a metallic step, G,nsecured in a base, D, made of marble or other'material suieiently heavy to hold theapparatus firmly in a vertical position, er so that it will not tip over. A plug, 0, provides for filling the reservoir. One or more lmetallic supply pipes, E, extend outward from the central tube B, and a regulating supply-cock, F, is arranged in said pipe or pipes; One end of a supporting-tube, G, screws into the outer end of the pipe E, and extends outward a short distance, and is curved downward, forming a quarter circle, then round 'and upward about a half eircle,i'the end turning upward vertically, and a collar, a, secured t'heretoaI short distance from the end.l A metallici conducting pipe, b, is arrangedwithin the tube G, and the ends of both are soldered together. A metallic conducting-wire, e,'.pass'es through the pipe b, and both ends project -a little beyond the ends of the tubes. The object of this conducting-wire is to cause an even iiow of iuid through the pipe b, and prevent the luid going through in drops or irregularly. I surround the outer vertical end of the tube G with a tube, of. cork, or other suitable non-condueter,f, which rests on the top of the collar a, and'isA held down bya nut, e, screwed on rto the outer top end of the tube G. A sectional tube, I,

large at the bottom end, and tapering-within, ts snugly lon to the insulatorf, and has a vapor-chamber, d,

above the insulator. The upper portion of the tube I is much smaller, and has a small interior, extending upward to within the shank of the top button g; The top end of the upper section t of the tube I has a. ser rated edge, and thivapor from the chamber d passes upward and over. the serrated edge, andinto the gaschamber le within ,the bulb. A metallic wire, X, extends from the top of the aperture in the shank. of the button downward into` the vapor-chamber, and its lower end is coiled or twisted, and rests in a packing ofcotton `or other light substance.

In'using my improved lamp the cock Fis turned to admit a small quantity of iiuid through the pipe b into -the lower part of the vapor-chamber rl. A dame is held in Contact with the bulb, which forms the gas chamber lc and the button g. Heat passes down the button and its shank and the wire m to the fluid-saturated cotton in the vapor-chamber d, causing vapor to `rise and pass over the serrated top edge of the 4tube i into the gas-chamber t, -wheregas is formed by the heat applied to the bulb. The gas passes out at small holes around the-under side of the bulb and ignites. The flame first named may then be removed, and the cock Fgradually `opened to admit a`full supply of fiuid through the pipe b around the wire c. The heat passing down the wire a' generates vapor quite rapidly, and the pressure of such vapor and the gas within the bulb prevents the fluid flowing too rapidly into the vapor-'chamber d, cverrthough the cock F is wide open. After this lamp has been lighted it will continue to burn with a beautiful iiame so long as the reservoir is kept supplied with suitable fluid, and the supplycock kept open. Closing the supply-cock extinguishes the flame in a short time. Consid-l .erable heat passes down the tubes It and I to generate vapor in the chamber d, 4and the insulatorf prevents the escape and loss of such heat, and without the insulator the heat passing down the tube I would passalong the supporting-tube G, and be of `so litt-le effect as to prevent or seriously retard the generating of vapor in the ,vapor-chamber. It will bo readily seen thdt the space between the tubes G and b prevents the possibility of heat being conducted to the fluid within the tube b, sothat volatile oils or fluids ,may be used in this lamp with perfect safety. l i i I Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A gas-generating and gas-burning lamp, constructed and arranged to operate silbstantially'as :and for lthe purpose specified.

2. 'lhc insulatorf, arranged and applied substantially as and for -thepurpose set forth.. 3. The arrangement of the tubes or-pipesG and Z1, whereby the fluid is protected from the action of external heat, substantially as set forth.
